ROLLER BEARING HK0810
The HK0810 is a single-row, drawn-cup needle roller bearing without an inner ring. It is designed for compact radial load applications where the shaft itself serves as the inner raceway. This bearing is ideal for use in limited-space mechanical assemblies, tools, motors, and light to medium-duty applications.

Construction & Features
Outer ring: Thin-walled steel drawn-cup serving as outer raceway.
Needle rollers: Multiple small cylindrical rollers providing high radial load capacity.
Cage: Steel cage holding the rollers in position.
No inner ring: The bearing rides directly on the shaft, saving space and cost.
Open ends: Both axial ends are open; suitable for lubrication via grease or oil.
Advantages
High radial load capacity in a compact design.
Space-saving, ideal for limited radial height applications.
Cost-effective and easy to install.
Suitable for light to medium-duty, high-speed applications.
